' 2 SHEETS-SHEET 2 heads 29 from thewindow casing during the sliding movement of the device when an 'efl'ort is made to raise the sash by the liftreadily opened or closed with the opening and closing of the sash. This plate 35 has an outstanding finger engaging lip 37 and an butstanding pin 38 located below the lip 3?. The ring 34: is adapted to engage over the pin w'hen it is desired to open the windew and unwind the screen at the same time. The screen can be manipulated independently of the sash, if desired, and the ring 34 operates as a lifting device and means for releasing the s ring-pressed locking bolts.

This manner or connecting the liftlng de vices of the sash and screen together aifords ready detachment of the screen from the sash, so that the latter can be opened independently of the screen, as when the window stant-ially the same.

panes are to be cleaned. 'Also in winter time, when. the screen is not required, it

can be conveniently detached from the window sash.

Where wide windows are employed, two

0:1 these slidable lifting devices may be empioyed, as shown at 35 in Fig. 6, in which case, thecables 32, which are connected to the locking bolts 28*, are secured to the ends 'or a bar 36 located longitudinally within the casing. This bar has upstanding terminals 37*, which are provided with rings .38 adaptedto be engaged over the holding pins 39" of the locking devices. A central actuating stem 40, secured to the bar 36 and projecting from the casing, constitutes means for turning the bar in order to engage the rings or disengage them from the pins.

The operation of both structures is sub- If the screen is not in use, the casing is left in its lowered position and the window sash may be raised or lowered as desired. \Vhen lowered, it abuts against the plate 9 in advance of the llange 11. It will thus be evident that said plate constitutes an effective covering for 'the roller and screen and the llange prevents water driving beneath the sash and passing into the space 10 in which the roller and screen are housed. When it is desired to screen the window, the ring illol the structure disclosed in Figs. 1-5 inclusive, or the rings 35 of the modification illustrated in l' ig. (i, arecngagcd with the pin Illl or the pins 39 as the case may be. and the sash is elevated by moans ol the lo king devices. it

will be evident that inasmuch as llwsc dcvicos have u lllllll((l movvnu-ul with respect to the sash, llio lirsl a tion i lo draw the bolls inwardly. but \Ylwu llw 11 l1 begins to mow ujnvardly. llw rrwn will mow with it.

As soon as the window has lu-nn raised d the lifting devices released, the springs 28 will. react to force the bolts outwardly and thus lock the screen and relieve the sash of the strain thereof. In lowering the sash, the lifting devices are held in their uppermost position by the fingers, while the sash is pushed downwardly.

From the foregoing, it is thought that the construction, operation and many advantages oi? the herein described invention will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape, proportion and minor details of construction, may be resorted 'to without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination with a window frame including an end wall comprising spaced inner and outer sections, of a plate overlapping the outer wall section and extending over the space between said sections, said plate having an outstanding flange along its inner edge that is disposed adjacent but in spaced relationto the outer edge of the inner wall section, a Window-sash movable in the frame and abutted against the plate outside the flange-at the limit of its movement,

a roller journaled in the space between the Wall sections, a screen that wraps upon the roller and moves between the flange and the inner Wall section, and means for connecting the screen to the sash.

2. The combination with a window frame including an end wall comprising spaced inits movement, ears carried by the plate and projecting into the space between the wall sections, a roller journaled in the cars, a screen that wraps upon the roller and moves between the flange and the inner wall section, and means for connecting the screen to the sash.

3. The combination with a window frame having a chamber provided with a slot, of a roller journalcd in the chamber, a screen that wraps upon the roller, a sash operating in the frame, a-casing having depending plulcs arranged to enter and till the slot when the screen is in closed position that are clamped upon the free end of the screen, oppositely movable holding bolts located in the ends of the casing and projecting therei'rom, means for independently holding the togetl'ier to open or closed position.

season is bolts in lockingposition and means carried by the casing for detachably connecting the same and thereby the screen to the sash.

4. The combination of a window frame, a sash slidably mounted therein, a self-wind ing screen mounted on the window frame, means on the screen for trictionally engaging the Window frame to hold the screen open at diti'erent positions, a lifting device attached to the screen and operatively con nected with the said means for disengaging the same from the window frame, a movable lifting device for the sash slidably mounted on the latter-t and means for directly detach ably connecting thelilting devices together to open or close the sash and screen simultaneously or permit independent movement of either.

The combination of a window frame, a sash mounted therein, a selt-winding,- screen, elements" on the screen for frictionally engaging the window frame to hold the screen open to different positions, a device opera- Lively connected with the elements for releasing the same, a lifting device mounted on the sash and arranged to have limited movement independently of the latter, and

means for opcratively connectingthe said.

devices together whereby the last-mentioned device operates through the first-mentioned device to release the elements and hold the same released during the movement of the sash and winding or unwinding of the screen.

G. The combination of a window frame having a slot, a window sash mounted thereon, a self-winding screen mounted on the frame and movable through the said slot, a member connected with the free end of the screen to form-a closure for the slot when the screen is completely closed, elements carried by the member to frictionally engage the window frame to hold the screen in dillerent open positions, an actuating device for the sashlmovably mounted thereon, an actuating device for the elements and for the screen, means for connecting the two device's together whereby the former operates through the latter for, releasingthe said elements and thereafter to move the sash and screen 7. The combination of a window frame, a sash thereon, a self-winding screen mounted on the frame, an actuating device movably mounted on the sash, means carried. by the screen for releasably ()rip'ping the window frame to hold the so/Jeen in different open mounted on thesash, a gripping member.

arried by the plate, spring-pressed bolts on the screen for cn ngnn the window frame to hold the screen in til .erent open positions,

a device connected with the bolts to release the same, end a'detachahle connect-ion be tween the device and said, plate 9. The combination with a window frzzme including a sill, of a spring roller located therein, a screen that wraps upon the roller, a casing connected to the screen andheving oppositely movable bolts that the window frame to hold said screen, springs for urging the bolls into engagement Wit 5 the frame, a vertih'ally slidahlesash, a liliti ing device for the sash slidahly mounted thereon and. having a projecting pin, flexible elements connected with the bolts and a ring connected to the elements and adapted to en gage with the pin of the lifting device.'
